If a ₹30,000 illustrative premium is added to loan principal, your cost is not only ₹30,000: interest can accrue on that financed amount according to the loan terms. Ask the lender for the KFS and disbursal statement so you can see whether the premium reduced net disbursal or increased principal.
Compare that with an appropriate standalone policy only after matching the insured person, benefit amount, duration and exclusions. A cheaper premium is not automatically equivalent protection.
